Abstract
Magnetic flux density contours developed by quadraturedriven, Nuclear Magnetic Resonance (NMR) radio frequency coils are investigated. Experimental data is obtained from symmetric and asymmetric structures of both circular and elliptical cross section. Said field profiles are analytically analyzed via a voltage- current transmission matrix model, utilizing an equivalent lumped- element circuit representation and yielding acceptable correlation with experimental data. In the worst case, for the elliptical asymmetric structure, the predicted magnetic flux density values agree to within 23.5% at most for measured values of the NMR flip angle . In the best case, for the circular symmetric structure, the predicted magnetic flux density values agree to within 7.4% at most for measured values of the NMR flip angle.
